cylinderical roller bearings

Cylindrical roller bearing

Cylindrical roller and raceway are linear contact bearings. Load capacity is large, mainly bearing radial load. The friction between the rolling body and the retaining edge of the ring is small, and it is suitable for high-speed rotation. According to whether the rings have retaining edges or not, it can be divided into single row cylindrical roller bearings such as NU, NJ, NUP, N, NF, and double row cylindrical roller bearings such as NNU, NN. The bearing is a separable structure of inner ring and outer ring.

The inner ring and outer ring of cylindrical roller bearings without retaining edges can move relative to the axis, so they can be used as free end bearings. Cylindrical roller bearings with double retaining edges on one side of inner ring and outer ring and single retaining edge on the other side can bear a certain degree of axial load in one direction. Generally, steel stamping cage or copper alloy solid cage are used. But some use polyamide to form cages.
